Like a good many other people, Biden seems to have suspended all critical thinking when it comes to gender ideology. He and his team and many other Democrats seem to have blinded themselves to all the evidence from Europe casting doubt on the hormonal and surgical treatments being offered to trans-identifying minors. They are ignoring the obvious problems with using gender ID in sport rather than sex to decide who competes in women's events. They are (utterly shamefully) pressing on with allowing gender self-ID in the prison system! How can anybody think that's a good idea?
This thread (link below) makes very grim reading. I updated it the other day. Biden put out a message of support condemning transphobic bullying in schools, having swallowed whole the narrative that this very troubled teenager had committed suicide because of an incident at school the previous day. He and his advisers have totally ignored the facts of this very sad case, which are in the public domain - the girl had experienced years of horrific sexual abuse from her own father, who served a prison sentence as a result. She had diagnosed mental health problems and was known to self-harm.

I don't think Trump is following this topic in any detail either, nor do I think he's capable of doing so. He just sees it as a useful way to attack the Democrats. They are making it very easy for him.
